Specifications

excellent lubrication,effectively reduce torque, wear and fatigue of the drilling, extend the entire life cycle of bit bearing

Our oil drilling graphite powder has excellent lubrication, so can effectively reduce torque, wear and fatigue of the drilling, to extend the entire life cycle of the bit bearing. And also able to reduce the frictional resistance of the drill string, shorten the trip time; and prevent stuck, bit balling. The graphite powder can be strongly adsorbed in drilling tool and side wall, so as to improve the state of the friction between the friction pair, to play a role in reducing friction. Meanwhile, graphite powder adsorption in the side wall, the side wall microvoid can be closed, so can achieve double effects on reducing the filtration of drilling fluid and protecting reservoirs.

Q: What are the hazards of inhalation of graphite dust?: It must be harmful to human beings! Look at the dictionary of carbon black dust lung disease Description: black carbon pneumoconiosis: long-term inhalation of carbon black dust caused by pneumoconiosis. Carbon black is mainly the quality of easy flying carbon. Although the production has been closed and automated, the phenomenon of dust flying still exists. Therefore, workers who produce and use carbon black may have black carbon pneumoconiosis, the shortest length of onset is 15 years, the longest can be more than 25 years, the clinical symptoms are mild, and the progress is slow, and generally does not affect the ability to work.

Q: What's the conductivity of graphite powder, silver powder?: The resistivity of silver is about 1.6*10-8.M at room temperature

Q: Classification of graphite powders: Grand powder (anti sealing grease) properties and uses: high temperature of 3000 degrees Celsius, high pressure 40KG, used for ships, aircraft, locomotives, automobiles, engineering machinery and all kinds of large-scale oil, chemical industry, electrical machinery and metal binding surface, the flange seal parts and anti sticking.Special graphite coating: paint, water-based graphite conductive graphite coatings, deposited graphite coating, graphite coating, graphite coating inside and outside the drawing, coating, glass coating, lubrication of graphite graphite TV and special coatings, non metal materials, nano materials, production process design. Deal with all kinds of anti-corrosion equipment, undertake all kinds of anti-corrosion equipment processing. Various varieties, specifications complete, the implementation of the "People's Republic of China national standards.". Special machinery design and manufacture all kinds of fine chemical equipment, various grinding machines and formula process.

Q: Whether the lubricating oil toner is coupled with the conductor?: You don't want to lubricate the rheostat. The metal piece in it is in direct contact, so even the lubricating insulator won't make any difference (as long as you don't rub it too much).

Q: Can graphite powder be used for concrete?: The graphite powder is soft, black and gray, greasy and polluting paper. Hardness is 1~2, along the vertical direction with the increase of impurities, its hardness can be increased to 3~5. The specific gravity is 1.9~2.3. Under isolated oxygen conditions, the melting point is above 3000 degrees Celsius and is one of the most refractory minerals.

Q: Like the wolf, adding graphite powder in the failure of electronic instrument air explosion in aircraft rocket season, really make it: If you want to hit the plane down, EMP is more practical! Besides, it is also expensive than with stinger!

Q: What mask should be used to prevent stone powder?: As an enterprise employee, we must actively advocate the right of labor protection to the enterprise owner, and the stone powder can be worn with industrial masks

Q: Crystal graphite of graphite powder: At room temperature, lambda A is about 200 times larger than lambda C. As the temperature increases, this ratio decreases, but remains large. Therefore, the thermal conductivity of polycrystalline graphite composed of microcrystalline is controlled by the thermal conductivity of microcrystalline layer lambda a, and lambda C can hardly be considered. The lambda a of natural flake graphite is between 280 and 500W/ (m * K) at room temperature. The ratio of lambda a/ lambda C is between 3~5, so the perfection of crystal is far better than that of high directional pyrolytic graphite.

Q: What is the ratio of the coated sand to the graphite powder? How to improve the refractoriness of precoated sand: In addition to improve the refractoriness with graphite, can also add red. It also plays a role in increasing refractoriness and reducing gas output.

Q: What kinds of graphite powder has it? What's the function?: The graphite powder can be divided into colloidal graphite powder and graphite powder, both of which are graphite products, and the colloidal graphite powder is colloidal
